Is global warming caused by humans


Global Warming is Human Caused. Scientists have concluded that most of the observed warming is very likely due to the burning of coal, oil, and gas. This conclusion is based on a detailed understanding of the atmospheric greenhouse effect and how humanactivities have been tweaking it.

Engine light on code reads bad cat replaced it light returns reads ox senors replaced it light returns reads cat gone bad.


the ECU (brain) has no idea at ALL what is broken!
it only knows 2 things, bad inputs. and failed tests.
nothing else. The brain is not AI (artificial intelligence)
Not even and expert system , yet.
that is the job of and ASE mechanic
to find the cause. and not GUE$$.

your failure to state the DTCs reported , sorry, is bad news to anyhelper, sorry!
420s. is , weak CAT test. but in most case it's not the CAT.
senors replaced? 1 or both.? B1S1 and B1S2?

Did you get o2 (oxy) DTC failures?, if yes, ignore all cat fails.!
if other codes/ DTC, that too, means ignore cat failure.
the CAT monitor (P042x) only is valid if the engine runs prefectly.
if not the CAT overheats or underheats( goes dead cold)\

the cat will over heat, (cel flash madly) for gross engine over fueling (1 example , bad fuel reg, and pressure at 60PSI)
the cat glows red hot , or near. and the test may fail.
case 2: the engine (AFR fuel) is grossly lean the CAT may go under temperature and drop off line.
we call this CAT no lit off, it has a minium working temperature.
as air leaks in front of the cat causes EFI to go very rich.
and leaks behind can make the rear 02 go nuts. and lie
and say, bad Cat.
all this is the domain of the ASE mech. he knows all stuff.
and never ever lets the ECU tell him what to do.;
it does tell him (suggests) a battery of test.
sure.
hope that helps,
post all stored, DTC,all pending and the full freeze frame data
and if cagey? the closed loop status hot idle.

Underheat


Similar concern for the 3.8 V-6...or the 4.6 V-8...the least costly problem is usually a worn out..(stuck open) thermostat. I assume no water leaks? Most costly can be the heater core, due to extensive labor time...Be sure to use OE rated thermostat that opens at 195 degrees...for performance not heat, a 160 degree thermostat is available...but not good for heat build up...not a big job on your Mustang...Hope this helps.

2004 ram3500 transmission slippage when warm


Hi, transmission slipping normally does not occur when the transmission is warm, as warm temperatures favor proper working of the automatic transmission systems. Nonetheless, if problems such as, broken transmission bands, gears or torque conversion already exist, then the transmission might slip even in warm temperatures. Another situation may arise, if the fluid suffers from contraction in cold weather and gradually the weather warms up sufficiently, to expand the internal parts and fluids. Then due to cold weather, a small transmission problem might occur. However, the problem may be too small to affect the vehicle. However, warm weather cannot be directly linked to transmission slipping.

How much warm up time does a dodge sprinter 2500 diesiel require in the winter time?


At idle it can take hours to fully warm up

If your concerned about driving it right away after starting, not a big issue.....start, let it warm a min or two then drive.

Diesels warm slower than gas engines, and they take longer to get warm enough to give you heat untill fully warmed up.

Normally you should see good temp and good heat after driving about 15 minutes after the first cold start of the day.

Warm up


The high idle is caused by the choke and the high idle on the carb. It is working normal and you do won't to warm up this motor before going. When it is warm and you hit the gas it activates the choke pull off to bring the idle to normal. Your mechanic is used to fuel injection that will control the fuel/air mix according to temp. I still let my injected cars warm up so the oil can thin a little. If you jump on the highway with cold thick oil it can all wind up in the to of the motor.
